A moratorium on any new oilsands expansion is imperative given Canada’s failure to properly assess the total environmental and climate impacts Canadian and U.S. experts say in the prestigious science journal Nature.

Even with a moratorium it will be very difficult for Canada to meet its international promise to reduce CO2 emissions that are overheating the planet according to government documents as previously reported by DeSmog.

“Continuing to approve pipelines and new projects guarantees Canada will not meet the Harper government’s Copenhagen emissions reduction target,” said Wendy Palen, an ecologist at Simon Fraser University.

“These are the plain facts Canadians need to be aware of,” Palen, a co-author of the Naturecommentary, told DeSmog.

Canadians also have no idea of the overall ‘big picture’ of the impacts of oilsands production and transport because each project is assessed in isolation.

In total more than 280 square kilometres of boreal forest and peatlands have already been eliminated to make way for oilsands development. That amounts to an area more than twice the size of the City of Vancouver.

According to a 2012 study the destruction of this region of the boreal forest – a natural carbon sink –released about 100,000 tonnes of CO2 that had been safely stored underground. And it also meant the end of the region’s ability to absorb some 58,000 tonnes of CO2 every year. Over a 20-year time span that’s 1,161,000 tonnes of CO2 that stays in the atmosphere – close to half the annual emissions of the City of Vancouver.

This does not include CO2 emissions from developing oilsands projects themselves nor the emissions from burning millions of barrels of oil produced there each year.

This piecemeal approach is like determining the risk of cigarette smoking by only looking at the potential harm from smoking one cigarette, environmental economist Mark Jaccard said.

As critics have pointed out during recent pipeline review processes, regulators like the National Energy Board do not consider the climate impacts of pipelines and oilsands projects. It’s considered ‘out of bounds’ Jaccard, another coauthor of the report, said.  Each project is presented as an ultimatum: approve the project or lose an economic opportunity, he said.

“This approach artificially restricts discussion to only a fraction of the consequences of oil development,” Jaccard and 7 co-authors argued in the report. The authors represent an interdisciplinary group of experts in environmental science, economics, policy development and decision science.

What Canada and the U.S. need is a “more coherent approach” to evaluate all oilsands projects and pipelines in the “context of broader, integrated energy and climate strategies.”

But first Canada and the U.S. need to impose an immediate halt to new oilsands developments and related pipeline construction, the authors write. (The U.S. is considering developing its own oilsands in Utah and elsewhere). Then the two countries can jointly develop a strategy that allows energy developments to proceed only if they are within environmental limits and respect other national commitments to human health, social justice and biodiversity protection.

However this strategy would need a formal, legislated acknowledgement of the reality that oilsands development impacts the climate. It also should create either a carbon tax or cap-and-trade mechanism to ensure the oil industry absorbs “the full social costs of carbon combustion.”

Finally this strategy should assess the full range of potential impacts compared to alternatives. And it should include the options of saying ‘no’ to a project.

Former Secretary of State Hillary Clinton said Canada and the U.S. need to co-ordinate their climate policies in an interview on the CBC’s The National last week. She acknowledged we need to get beyond project-by-project approvals.

With new regulations on power plants, the U.S. may be on its way to meeting its Copenhagen emission reduction target, which is identical to Canada’s.

While Prime Minister Harper “clearly doesn’t care about climate change,“ Jaccard told DeSmog,  President Obama does and could make approval of the Keystone XL pipeline contingent on Canada meeting its 2020 target.

“Economists around the world now agree the costs of carbon pollution far outweigh the benefits,” Jaccard said.

We Have Five Years to Stop Building Coal Plants and Gas-Powered Cars

Measurement of CO2 levels in atmosphere

By Stephen Leahy

[Authors note: One of the most difficult and important articles I’ve written in 20 years of environmental journalism. Originally published Sept 6 2014 @Vice Motherboard]

 

Here’s the frightening implication of a landmark study on CO2 emissions:

By 2018, no new cars, homes, schools, factories, or electrical power plants should be built anywhere in the world, ever again, unless they’re either replacements for old ones or carbon neutral. Otherwise greenhouse gas emissions will push global warming past 2˚C of temperature rise worldwide, threatening the survival of many people currently living on the planet.

Every climate expert will tell you we’re on a tight carbon budget as it is—that only so many tons of carbon dioxide (CO2) can be pumped into the atmosphere before the global climate will overheat. We’ve already warmed temperatures 0.85˚C from pre-industrial levels, and the number rises every year. While no one thinks 2˚ C is safe, per se, it’s safer than going even higher and running the risk that global warming will spiral out of our control completely.

Last year, the latest Intergovernmental Panel on Climate Change (IPCC) report established a global carbon budget for the first time. It essentially stated that starting in 2014, the carbon we can afford is up to around 1,000 billion tons of CO2. In other words, our cars, factories, and power plants can only emit 1,000 billion tons (1,000 Gt, or gigatons) of CO2 into the atmosphere if we want to have a greater than 50/50 chance of keeping our climate below 2˚C of warming.

Even considering that humanity pumped 36 gigatons of CO2 into the atmosphere last year alone, 1,000 Gt still seems like a big budget. It might even seem like we have room to spare.

Maybe not.

WORLDWIDE, WE’VE BUILT MORE COAL-BURNING POWER PLANTS IN THE PAST DECADE THAN IN ANY PREVIOUS DECADE

New research shows that we may not have been paying attention to the entire CO2 emissions picture. We’ve only been counting annual emissions, and not the fact that building a new coal or gas power plant is in reality a commitment to pumping out CO2 for the lifespan of a given plant—which usually ranges from 40 to 60 years. These future emissions are known as a carbon commitment.

A new study has tallied the carbon commitments from all existing coal and gas power plants by looking at their annual CO2 emissions and current age. The study assumes an operating life of 40 years. A 38-year old coal plant will have far smaller future CO2 emissions, and thus smaller carbon commitment than one built today. The study, “Commitment accounting of CO2 emissions,” determined that most new power plants that went online in 2012 have a very large carbon commitment—19 Gt of CO2.

Building new power plants means more carbon commitments to eat into our 2˚C carbon budget. Build enough giant coal plants today, and their future emissions would tie up the entire budget, leaving no room for any other source of CO2 emissions.

Meanwhile, the rate at which new plants are built far outpaces the closure of old plants. Many US coal plants operate for longer than 40 years; the oldest is currently around 70 years.

“Worldwide, we’ve built more coal-burning power plants in the past decade than in any previous decade, and closures of old plants aren’t keeping pace with this expansion,” said study co-author Steven Davis of the University of California, Irvine.

Fossil Fuels Power Plant Carbon Commitment: 300 Gt

In the study, Davis and co-author Robert Socolow of Princeton University calculated that the existing coal and gas power plant carbon commitment turns out to be very large—more than 300 Gt.

Non-Power Plant Carbon Commitment: 400 Gt 

The reality of carbon commitment applies to any new fossil-fuel burning infrastructure, including office buildings and homes using gas heating or automobiles and planes burning jet fuel. All of these have an operating life of several or many years during which they will emit CO2 from now until they are ‘retired.’ These future emissions also count as a carbon commitment. In another upcoming study, Davis calculated the carbon commitments from other CO2 sources, including from the transport, industry, commercial and residential sectors. He estimates that as of 2013 this carbon commitment exceeded 400 Gt.

Together with the power plant commitment of 300 Gt laid out in the current study, that’s more than 700 Gt in carbon commitments on a global carbon budget of 1000 Gt. That leaves less than 300 Gt for future power plants, steel mills, cement plants, buildings, and other stuff that burns fossil fuels.

At current rates we’ll have accounted for the remainder of the budget in only five years.

Here’s how it breaks down:

Estimated Annual Emissions 2014-2018: 200 Gt

Global CO2 emissions from all sources amounted to 36 Gt in 2013. Annual emissions have been growing at a rate of 2 to 3 percent per year. Without major efforts to reduce emissions, another 200 gigatons of CO2 will be emitted between 2014 and 2018.

Estimated New Carbon Commitments 2014-2018: 100 Gt

Davis and Socolow determined that carbon commitments from new fossil fuel burning infrastructure will average at least 20 Gt per year, totaling 100 Gt over five years.

300 + 400 +200 +100 = 1,000 Gigatons of Carbon, Locked in by 2018

Unless coal and gas power plants or other major sources of CO2 are shut down before the end of their life span, the 1,000 Gt global carbon budget will be fully allocated sometime in 2018. No one will notice, because things won’t look or feel too much different than today. CO2 is akin to a slow, trans-generational poison. The climate impacts of blowing the carbon budget won’t be felt until 2030 or 2040 —and for a long time after.

WE’VE BEEN HIDING WHAT’S GOING ON FROM OURSELVES: A HIGH-CARBON FUTURE IS BEING LOCKED IN BY THE WORLD’S CAPITAL INVESTMENTS

Even the climate experts won’t notice much, because annual CO2 emissions have been the sole focus of countries and the United Nations process to address climate change said Davis.

“That’s like driving down the highway and only looking out of the side window,” Davis told me.

Politicians, business leaders, investors, planners, bureaucrats and whole lot of other people should be looking out the front window and paying attention to the hard reality of carbon commitments. If Davis and Socolow’s calculations are correct, it means no new coal or gas power plants can go online after 2018 unless they’re replacing retired plants. It means freezing the size of the global automobile fleet, and the industrial and commercial sectors, unless their energy efficiency increases. And so on.

The fact that much of our current and future infrastructure carries huge carbon commitments is blindingly obvious, but receives little attention.

Can’t solve a problem by making it worse

“If you build it, there will be emissions year after year. This should be a fundamental part of the decision to build most things,”” Davis said.

Ignoring the reality of carbon commitments means we’re investing heavily in technologies that make the problem worse, he said.

“We’ve been hiding what’s going on from ourselves: A high-carbon future is being locked in by the world’s capital investments,” said co-author Robert Socolow. Any plan or strategy to cut CO2 emissions has to give far greater prominence to those investments. Right now the data shows “we’re embracing fossil fuels more than ever,” Socolow told me.

So what can we do to begin to prepare for a jam-packed carbon budget? First, we need to stop building fossil fuel-reliant power plants.

Surprisingly, it appears the Australia is a pioneer here, despite recently rolling back its pioneering carbon tax. Thanks to wide-spread adoption of solar energy on homes and business the country’s electricity use is in steep decline. For the first time in its history, no new coal or gas power capacity will be needed to maintain supply over the next 10 years, according to the Australian Energy Market Operator. Germany too is rapidly adopting clean energy sources like wind and solar, so as to avoid building coal or nuclear power.

Next, we need to think about meeting energy demand by improving efficiency, instead of building more power generation.

Potential energy efficiency gains of 50 percent are possible across many sectors in most countries, Socolow said, and could reduce the number of fossil fuel energy power plants.

The US is the king of energy waste by most estimates. This costs Americans an estimated $130 billion a year, according to the Alliance to Save Energy. But despite the potential for huge cost and emission reductions, governments everywhere put nearly all their energy research efforts into new sources of energy like new power plants rather than helping to develop energy-efficient cars, buildingsm and appliances. It’s 2012 international study also found that improving energy efficiency provides by far the best bang-for-the-buck for energy security, improved air quality, reduced environmental and social impacts and carbon emission reductions.

However, efficiency improvements take time, and there is precious little time left to make the CO2 emissions cuts to stay below 2˚C, said Socolow.

While refusing to say a planet that’s 2˚C hotter is inevitable, he did say that all efforts to reduce emissions must be undertaken as soon as possible: “3˚C is a whole lot better than 5˚C, the current path we’re on.”

Japan Bails Out on CO2 Emissions Target

WARSAW, Nov 15 2013 (IPS)   Japan announced Friday that it will renege on its carbon emissions pledge, likely ending any hope global warming can be kept to 2.0 degrees C.

The shocking announcement comes on the fifth day of the U.N. climate talks in Warsaw known as COP19, where more than 190 nations have agreed to a 2.0 C target and are trying to close the carbon emission gap to get there.

“It’s like a slap in the face of those suffering from the impacts of climate change such as the Philippines.” — Wael Hmaidan

Japan will increase that gap three to four percent with its new 2020 reduction target, according to the Climate Action Tracker (CAT). It amounts to a three-percent increase compared to a 1990 baseline. Japan’s 2009 Copenhagen Accord pledge was a 25 percent reduction by 2020.

“Japan is taking us in the opposite direction,” Marion Vieweg of Climate Analytics, a German climate research organisation, told IPS here in Warsaw.

“Their revision shows the bottom up approach is not working if countries can simply drop their pledges at any time,” Vieweg said.

Climate scientists have long maintained that the 2020 target for industrialised countries should be to reduce emissions 25-40 percent compared to a 1990 baseline. However, even if nations meet their current climate pledges under the Copenhagen Accord, CO2 emissions in 2020 are likely to be eight to 12 billion tonnes higher than what’s needed, according to the U.N. Environment Programme’sEmissions Gap Report 2013.

Japan, the fifth largest emitter of CO2, is just the latest to abandon its international commitments.

“Canada is not a country, it’s winter,” Canadians say with pride. But the nation’s long, fearsome winters will live only in memory and song for Canadian children born this decade.Winters are already significantly warmer and shorter than just 30 years ago. The temperature regimes and plant life of the south have marched more than 700 kilometres northward, new research shows.

The frozen north is leaving and won’t be back for millennia due to heat-trapping carbon emissions from burning fossil fuels, experts say.

By 2091, the north will have seasons, temperatures and possibly vegetation comparable to those found today 20 to 25 degrees of latitude further south, said Ranga Myneni of the Department of Earth and Environment, Boston University.

“If we don’t curb carbon emissions, Arctic Sweden might be more like the south of France by the end of the century,” Myneni, co-author of the Nature Climate Change study published Sunday, told IPS.

That number was 52 billion tonnes of CO2 in 2012

Only when this number declines will we know we’re making the shift to climate protection

By Stephen Leahy

UXBRIDGE, Canada, Dec 17 2012 (IPS) 

The most important number in history is now the annual measure of carbon emissions. That number reveals humanity’s steady billion-tonne by billion-tonne march to the edge of the carbon cliff, beyond which scientists warn lies a fateful fall to catastrophic climate change.

With the global total of climate-disrupting emissions likely to come in at around 52 gigatonnes (billion metric tonnes) this year, we’re already at the edge, according to new research.

To have a good chance of staying below two degrees C of warming, global emissions should be between 41 and 47 gigatonnes (Gt) by 2020, said Joeri Rogelj, a climate scientist at Switzerland’s Institute for Atmospheric and Climate Science in Zurich.

“Only when we see the annual global emissions total decline will we know we’re making the shift to climate protection,” Rogelj told IPS.

Making the shift to a future climate with less than two degrees C of warming is doable and not that expensive if total emissions peak in the next few years and fall into the 41-47 Gt “sweet spot” by 2020, Rogelj and colleagues show in their detailed analysis published Sunday in the journal Nature Climate Change.

The study is the first to comprehensively quantify the costs and risks of emissions surpassing critical thresholds by 2020. Continue reading →

Re-engineering our societies to prosper on green alternatives is only option

By Stephen Leahy

UXBRIDGE, Canada, Jan 4 2013 (IPS)

Around the world, 2012 was the year of extreme weather, when we unequivocally learned that the fossil fuel energy that powers our societies is destroying them. Accepting this reality is the biggest challenge of the brand new year.

Re-engineering our societies and lifestyles to prosper on green alternatives is the penultimate challenge of this decade.There is no more important task for all of us to engage in because climate change affects everything from food to water availability.

A number of scientific analyses have demonstrated we already have the technology to re-engineer our society to thrive on green alternative energy. The newest of these was published Wednesday in the prestigious journal Nature. It plainly states that politics is the real barrier, not technology nor cost. (It is far cheaper to act than not.)

Keeping global warming to less than two degrees C is mainly dependent on “when countries will begin to take serious action to reduce greenhouse gas emissions”, according to the study “Probabilistic cost estimates for climate change mitigation”.

Climate change has already pushed global temperatures up 0.8 degrees C, with significant consequences. No climate scientist thinks two degrees C will be “safe”. Many countries, especially least-developed countries and small island states, want the global target to be less than 1.5C of heating. Even then large portions of the Arctic and Antarctic will continue to melt raising sea levels, albeit at a slower rate.

Delay in making the shift to non-fossil fuel energy sources will be very costly. Waiting until 2020 to curb global emissions will cost twice as much compared with peaking emissions by 2015, the Nature analysis shows.

Serious action to reduce greenhouse gas emissions means 65 percent of current coal power plants will have to be shut down in the next decade or two, a previous Nature study reported by IPS shows.

New study reveals a major trend is underway. More and more countries are acting on climate – only Canada going backward

By Stephen Leahy

UXBRIDGE, Canada, Jan 15 2013 (IPS) 

A majority of major economies have made significant progress in addressing climate change, with countries like South Korea and China taking aggressive action so they can benefit from energy- and resource-efficient economies, a new report released Monday found.

The study by GLOBE International and Grantham Research Institute profiled 33 major economies in an annual examination of climate and energy legislation. 32 of them, including the United States, made significant progress in 2012, while only Canada regressed.

“The study reveals a major trend is underway. More and more countries are acting on climate,” said Adam Matthews, secretary general of GLOBE International, an organisation of legislators.

While major international climate conferences such as the Conference of the Parties (COP) held in Doha in November and December 2012 have made little progress, cities, states and national governments around the world are taking action.

The political reality, Matthews told IPS, is that local and national climate regulations and legislation must come first. “An environment minister in Doha couldn’t commit his country to an ambitious carbon reduction target unless the country has already decided to chart a new economic course,” he said.

It doesn’t have to be this way – typical family could reduce their energy use 60 to 75 percent

UXBRIDGE, Canada, Jan 29 2013 (IPS)

Weird is the only way to describe January temperatures whipsawing between record warm and arctic cold over a span of a few days. Experts say that is what climate change looks like: weird, record-shattering weather.

Here’s a fact that goes beyond weird to astonishing. Anyone who is 27 years old or younger has never lived through a month that was colder than the global 20th century average. In other words, we’ve had 334 consecutive months with above average temperatures, according to the U.S. National Oceanic and Atmospheric Administration.

Last summer, the Arctic sea ice shrunk to half of what it used to be during summers only three decades ago. Our planet’s weather is driven largely by the two cold polar regions and the warm tropics. With the Arctic defrosting, it should be no surprise our weather is getting weird. And that it’s not going to get better.

Our planet is heating up because we each year put thousands of millions of tonnes of carbon dioxide (CO2) into the atmosphere by burning coal, oil, and natural gas. CO2 acts as heating blanket keeping the planet warm by trapping some of the sun’s heat.

The amount of extra heat-energy being trapped is like exploding 400,000 Hiroshima atomic bombs per day 365 days per year, calculates James Hansen, a climate scientist who heads the NASA Goddard Institute for Space Studies.

Cautious scientists like Hansen are terrified of what’s coming. Conservative institutions like the World Bank and accounting giant Price Waterhouse Coopers (PwC) have warned we’re on a path to heating the entire surface of the planet by an average of four or five degrees C before 2100. That translates into eight to 12 degrees C hotter in places like Canada.

Global Temperatures Rising on a Devastating Trajectory

Global temperatures are only 0.7C warmer — on pace for +4C!

By Stephen Leahy

UXBRIDGE, Canada, May 25, 2012 (IPS)

Climate-heating carbon emissions set a record high in 2011, in a 3.2 percent increase over the previous year, the International Energy Agency reported this week. The main reason for this dangerous increase is that governments are failing to implement policies to prevent catastrophic increases of global temperatures.

A new report released on the last days of international climate talks in Bonn, Germany this week reveals that the planet is heading to a temperature rise of at least 3.5 degrees Celsius, and likely more, according to the Climate Action Tracker (CAT), despite an international agreement to keep global temperature rise below two degrees Celsius.

Not only are pledges inadequate, but countries are unable to fulfill even those pledges, a new CAT analysis shows. CAT is a joint project of Dutch energy consulting organisation Ecofys, Germany’s Climate Analytics, and the Potsdam Institute for Climate Impact Research.

“When we compared the emission reduction pledges of countries like Brazil, Mexico and the U.S., we found they did not have the policies in place to meet those pledges,” said Niklas Höhne, director of energy and climate policy at Ecofys.

Höhne told IPS that they looked only at the policies of a few countries, but no country’s policies were enough to meet their targets. Continue reading →
